6 Claims.

This invention relates to improvements in windows of the type including a frame having an upper and a lower sash slidably mounted therein and counterbalanced by weights, said improvements more particularly being 'directed to improved means forming a partr of the window frame and sashes, whereby'the sashes upon removal of portions of the inner facing strips and of the parting beads may be pivotally swung inwardly from the frame about horizontal axes thereby permitting ready access to be had to the outer surfaces of the windowpanes to permit cleaning of the same orreplacement of the window panes in case they are broken.

It is an object of this invention to provide a window construction wherein the window sashes are adapted to be pivotally swung inwardly from the window frame to permit ready access to be had to the outer surfaces of the window panes.

It is also an object of this invention to provide a window construction wherein the window frame has the inner facing strips and the parting beads construction to permit portions thereof to be removed irorn the window frames to permit the window sashes to be equipped with temporary pivots permitting the sashes to beswung downwardly about the pivots to afford ready access to the outer faces of the window glass.

It is an important object of this invention to provide animproved type of window construction consisting of a window frame having counterweighted sashes slidably engaged therein and furthermore having the inner facing strips and the sash parting strips or beads constructed to permit removal of the lower `portions of said vstrips and beads to permit the window sashes to be equipped with removable pivots whereby first the'lower sash and then the upper sash may be pivotally swung downwardly about the pivots to permit ready access to be had to the outer surfaces of the window panes to permit cleaning of the same.

Other and further objects of this invention will be apparent from the disclosures in the specification and the accompanying drawing.

The invention (in a preferred form) l is illustrated in the drawing and hereinafter more fully described.

On the drawing:

Figure 1 is a fragmentary elevational view of the inner side of a window construction embodying the features of this invention.

Figure 2 is a vertical transverse section of the window construction having portions of the inner spacing strip and the parting bead removed and showing the window sashes equipped with -pivot means permitting the same to be pivotally swung inwardly into the dotted line positions to permit access to be had to the outer surfaces of the window sash panes.

Figure 3 is an -enlarged fragmentary detail section taken on line III-Ill of Figure 2.

Figure 4 is an enlarged fragmentary detail section taken on line IV-IV of Figure l.

As shown on the drawing:

The reference numeral l indicates a window frame including an outer sill 2 and an inner sill 3. Slidably mounted in vertical grooves d provided on the inner sides of the vertical members of the window frame, are lower and upper window sashes 5 and 6 respectively. The window sashes 5 and 6 have connected thereto sash cords l which operate over window pulleys 6 and have counterweights attached to the enclosed ends thereof in the ordinary manner.

The sash grooves d are formed between the outer facing strips 9 which extend the whole length of the window opening and inner facing )strips each comprising an upper inner facing strip section i6 and a removable lower inner facing strip section ll. The lower ends of the upper inner facing strip sections i@ are beveled as are also the upper ends of the lower inner facing strip sections li as indicated at iii in Figure 1. The removable lower facing strip sections ll have hidden surfaces i3 thereof (Figure 4). A pair of spaced latch springs M are secured to the surfaces` i3 of the removable lower facing strip sections il by nails i5 or other suitable means. To releasably hold the lower facing strip sections li in place against the side members of the window frames, the spring latching members lli releasably project through openings i6 provided in the vertical members of the frame l von opposite sides of the window opening.

Each of the window frame members il is provided with a pair of lower and upper internally threaded sockets l 8, each of which as clearly illustrated in Figure 3 comprises in detail an internally threaded stocket sleeve i9 held in place by means of a retaining sleeve 26 engaged therearound and driven into the frame member l'l. The two lower internally threaded stocket units i3 are mounted nearer the inner face of the window frame than are the upper pair of internally threaded sockets which are mounted farther in for cooperation with the upper sash as hereinafter more fully described.

The window sashes 5 and 6 are each provided .near the lower ends of the inner faces of said Cil sashes, with a pair of oppositely positioned internally threaded sockets 2| each of which comprises in detail an internally threaded socket sleeve iii and a retaining sleeve similar to the construction of the socket I8. Apertured face plates 22 are secured to the inner faces of the window sashes 5 and 6 to cover the ends of the socket members i9 and 2i) as clearly illustrated in Figure 3.

For the purpose of permitting the window sashes to be pivotally swung inwardly about horizontal axes when the lower facing strip sections ii and the lower removable parting strip sections or beads 23 are removed from the frame, each of the window sash sockets 2l is provided with a removable screw-eye 24. Projecting through each of the eyes of the screw-eyes 24 is a pivot shaft or aXis pin 25 provided with a head at the outer end thereof and having the inner end threaded for removable threaded engagement in the internally threaded socket sleeve i9 of the frame socket IB as illustrated in detail in Figure 3. The grooves 4 of the window frame are separated from one another by means of parting strips or beads each of which comprises a removable lower parting strip section 23 and a permanently mounted upper parting strip section or bead 24. The upper parting strip section 2li is illustrated in Figure 2 from which the lower parting strip section 23 has been removed, but which is shown in place in Figure 3.

Having described in detail the various parts forming the improved features of the window construction the operation thereof will now be briefly described. Normally the window sashes 5 and 6 are-slidably engaged in the grooves 4 and the lower parting strip beads 23 and the lower inner facing strip sections Il are secured in place within theV window frame to serve as guides for the window sashes. When it is desired to have access to the outer surface of the lower sash window pane from the inner side of the frame it is only necessary to pull the lower facing strip sections l1 out, in which case the latching springs i4 are compressed and slide through the openings I6 (Figure 4). The lower sash is now raised a slight amount and tilted until the lower sockets 2| are at the same level as the lower sockets i8. Screw-eyes 24 are then threaded into the lower sash sockets 2l and the pivot pins 25 are then projected through the eyes of the screw-eyes 24 and are threaded into the lower sockets It provided in the side of the window frame.

With the lower sash 5 in the full line position illustrated in Figure 2, the upper end of the lower window sash may be pivotally swung out of the window frame about the horizontal pivots or stud shafts 25, to permit the window cords to be pushed out of the cord grooves of the window sash to allow the window sash to be swung into the dotted line position illustrated in Figure 2, to expose the outer face of the window pane to permit a person within a room to conveniently clean the window pane.

After the lower sash has been pivotally swung inwardly into the dotted line position illustrated in Figure 2, the removable parting strip sections or beads are pulled out of the receiving grooves The upper sash having been moved downwardly in the frame to permit removal of the parting strips 23, is now equipped with screweyes 24. The lower end of the upper sash 6 is now pulled outwardly into the inclined position illustrated in Figure. 2 to permit the pivot pins or stud shafts 25 to be projected through the eyes of the screw-eyes 24, to permit the threaded ends of the stud shafts to be threaded into the upper pair of sockets I8. With the pivot means for the upper sash 6 in position as described, they upper end of the upper sash is now swung downwardly and the sash cords are pushed outwardly to permit the upper end of the upper sash B to be swung into the dotted line position illustrated in Figure 2 to afford ready access to the outer face of the window glass of the upper sash.

After the window panes have been cleaned, the window sashes 6 and 5 are returned to their normal position in the reverse order from which they have been released, that is the upper sash 6 and the parting beads 23 are first returned into position, after which the lower sash is returned into its normal position and the cycle of operations is completed by placing the lower facing strip sections H back into their normal positions by projecting the latching springs I4 through the frame openings I6.

It will, of course, be understood that various details of construction may be varied through a wide range without departing from the principles of this invention, and it is, therefore, not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.
